About:

From executive producer Steven Spielberg, Falling Skies stars Noah Wyle as a former college professor who becomes the leader of a group of soldiers and civilians struggling against an occupying alien force.

Moon Bloodgood co-stars as Anne Glass, a pediatrician who works with the surviving children to help them cope with the traumatic situation. The series also stars Drew Roy as Hal and Maxim Knight as Matt, Tom’s two sons; and Seychelle Gabriel as Lourdes, an orphaned teenager who helps run the group’s commissary.

In the third season of Falling Skies, Gloria Reuben is set to guest-star in a multiple-episode arc as Marina Perlata, an aide to Wyle’s Tom Mason. In addition, Robert Sean Leonard is slated to guest-star as Roger Kadar, an obsessive but gifted scientist who runs the local power grid and lives underground with his pet rats, earning him the nickname “The Rat King.”
